Product Specification
R
High pin count packages (especially ball grid arrays) can
not accommodate external termination resistors.
Virtex-II XCITE DCI provides controlled impedance drivers
and on-chip termination for single-ended and differential
I/Os. This eliminates the need for external resistors, and
improves signal integrity. The DCI feature can be used on
any IOB by selecting one of the DCI I/O standards.
When applied to inputs, DCI provides input parallel termina-
tion. When applied to outputs, DCI provides controlled
impedance drivers (series termination) or output parallel
termination.
DCI operates independently on each I/O bank. When a DCI
I/O standard is used in a particular I/O bank, external refer-
ence resistors must be connected to two dual-function pins
on the bank. These resistors, the voltage reference of the N
transistor (VRN), and the voltage reference of the P transis-
tor (VRP) are shown in
Figure 10
.
When used with a terminated I/O standard, the value of
resistors are specified by the standard (typically 50
).
When used with a controlled impedance driver, the resistors
set the output impedance of the driver within the specified
range (25
to 100
)
. For all series and parallel termina-
tions listed in
Table 11
and
Table 12
, the reference resistors
must have the same value for any given bank. One percent
resistors are recommended.
The DCI system adjusts the I/O impedance to match the two
external reference resistors or half of the reference resis-
tors, and compensates for impedance changes due to volt-
age and/or temperature fluctuations. The adjustment is
done by turning parallel transistors in the IOB on or off.
Controlled Impedance Drivers (Series
Termination)
DCI can be used to provide a buffer with a controlled output
impedance. It is desirable for this output impedance to
match the transmission line impedance (Z). Virtex-II input
buffers also support LVDCI and LVDCI_DV2 I/O standards.
Controlled Impedance Drivers (Parallel
Termination)
DCI also provides on-chip termination for SSTL3, SSTL2,
HSTL (Class I, II, III, or IV), and GTL/GTLP receivers or
transmitters on bidirectional lines.
Table 12
lists the on-chip parallel terminations available in
Virtex-II devices. V
CCO
must be set according to
Table 8
.
Note that there is a V
CCO
requirement for GTL_DCI and
GTLP_DCI, due to the on-chip termination resistor.
